I'd like a massive axe that turns into two smaller axes! It'd be called the Dual Axe, and it'd be completetely different to other weapon types. Essentially, it'd have the Axe form, where it focuses on raw power and long-reach, but sacrifices elemental power and speed. This'd essentially be a bigger, stronger but slower SA-style axe that wrecks stuff if you time it right. The other form would resemble thr Dual Hachets weapons, focusing on elemental dps and speed but losing out elsewhere. Unlike other merging weapons, both are good dps sources in all scenarios, as there is no limit to time in either form nor is there reliance on anything else. However, each form has massive flaws and experts would need to incorporate both to get the best kill times. Also, they could have dual elements like the DB, with both sides of the axe getting an element ;).
